How to create physics-based animation such as fling and spring animation in jetpack compose?
We will explore Compose animations API to create physics-based cool animations.
What we’re going to implement
- Spring release animation
- Fling animation
- Chain spring animations
But first, let’s get familiar with spring animation. Spring is physics-based animation, unlike other animations, it adds a more natural and smooth effect in motion.
In Jetpack compose, we have spring AnimationSpec to customize animations. SpringSpec takes three parameters.
- DampingRatio — define the bouncy of spring. The lower the damping ratio, the higher the bounciness. The default value is DampingRatioNoBouncy
- Stiffness — is something like animation duration, it defines the speed of spring to the final position. The default value is Spring.StiffnessMedium
- VisibilityThreshold — specifies the visibility threshold.

The difference between Kotlin vs Java.
Android has officially adopted Kotlin as the supported language.
Future of Android development will be change, developers should know the differences Kotlin vs Java.
Kotlin Android is introduced by Google to build interactive mobile applications.
This programming language helps developers to track each functional aspect of programming with accuracy.
Kotlin comes featured with a number of advantages that make it more preferable programming language by the developers.
After Google officially launched Kotlin, a lot of developers started taking interest in this new language that allows them to save hours of development time.
Infact, many developers have also started to learn about Kotlin open source libraries that help them build better Android apps than before.
Currently, Android Kotlin libraries are one of the hottest topics for all the Android developers as they want to explore different libraries so that they can to get huge help while developing apps.
Here’s the list of 6 awesome Android Kotlin Libraries shared by our one of our Android programmers who recently worked on an Android Kotlin project.
Kotlin allows you to define functions and properties at the top level of your files.
That’s a great feature, but it can cause some confusion when combined with the fact that all top level declarations are referenced unqualified from Kotlin.
This can sometimes make it difficult to tell what a function is when reading one of its usages.
If you have a function with the same name in a different package, it’s not obvious from looking at the call site which function is being called.
You can fully qualify the name of the function with the entire name of the package that it’s defined in, but given Java’s convention of very deep package names, that’s not ideal.

As of now, Kotlin targets Java and JavaScript and is executed on JVM.Kotlin has been developed taking inspiration from other programming languages like Java, Scala, Groovy, Gosu, etc .
The overall syntax of Kotlin, even though may not be entirely similar to Java, at its core, Kotlin is dependant on the existing Java Class library to get productive results for the programmers.What are some major advantages of Kotlin?Brevity:The language is based on JVM and on its functional language which greatly curtails the boiler plate code that is used by other programming languages.
While it still remains more readable and far more typesafe.
Secondly, language is more expressive and a functional one.
Performance:Kotlin delivers exceptional performance and miniscule runtime.
Interoperability:Kotlin is a mature language allowing for an interoperable application in an uncomplicated manner.Contemporary:Since it is a new, modern language which gives developers a fresh start when involved in Kotlin application development services.
